'To all whom 'it may concern:

` Be it known that 1, Henny F. Bronnen,

of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Rotary-Cylinder Web-Printing Presses; and I hereby declare that the 'following a lull, clear, and exact description thereof, reiference being had to the accompanying drawings, which form part of this specification.

This invention is an improvement in rotary cylinder web printing resses, and relates particularly to the press shown in my Patent No. 814,510, dated March i3, 1906, the object of the present invention being to enable such presses to produce multi-colored papers. A press of the size shown in my said patent if equipped with4 my present invention, can produce one 8-page or one 1lipage paper with both sides printed in color,

and byl the addition of two extra plate cylinders and inlring .mechanisms it can produce one S-page, or one iii-page, papel-one side of which can be printed in three colors in addition to .the black, and the other side of which can be printed vin one color and black. p The capacity or" the press can be va ried by varying the length ot the plate cylinders, so that the invention is not .limited to .one S-page, or a lli-page, press, and I simply mention that number oi pages for convenience of explanation. The number of pages produced will depend entirely upon the number of plates that the cylinders are adapted tocarry, and 'whether the plates are arranged for Straight run or collecting methods of printing, and also upon the number of printing sections in the press. In'ithe ,example shown the press has two such sections and will now describe the invention with reference to the drawings which will enable the same to he clearly understoodg and I reifer to the claims l'or summaries of the arrangements and constructions of parts for which protection is desired.

The invention, I remark, embodies a novel method of and means for threading the press, and other novel details which will be hereinafter referred to. e

In fthe drawings-Figure 1 is a plan view tof,the, complete machine threaded, the web Ibeing broken away in arts to more clearly indicate lthe leeds .oit tie webs; Fig. 2 is .a

diagramniatical transversc-section of the press lon the line 2 2, Fig. 1; and Fig. 3 is a sin'iilar section on the line 3nd, Fig. 1.

'As shown the press has two main sets of perfecting mechanisms, each comprising two plate cylinders and co-acting impression cylinders which are arranged. side by side at a substantially horizontal plane, all the cyl- .indors extending longitudinally oi' the press and the cylinders in the adjacent perfecting mechanisms being arranged end to end and extending longitudinally of the press, as in my patent aforesaid. Above and co-acting with one of' the impression cylinders in each perfecting mechanism is a third plate cylinder.

The plate cylinders in what I term the first perfecting mechanism are designated as 1, 2 and 3, and the impression cylinders -are designated by 1a and 2a, the plate cylindersl 1 and 3 co-acting with the impression cylinder 1n. The plate cylinders in the second perfecting mechanism are designated ly ll, 12 and 13, and the impression cylinders by 11, 12, the plate cylinders 11 und 13 both co-acting with the impression cylinder 111. Each plato cylinder is provided with an inlring-system, designated lo 1", 2*,- 3", 11x, 12`^ and 13"; these nking mec anisms are preferably constructed as shown and described in my Patent No. 823,098, dated June 12, 1906, and need no particular description herein, they being adapted to supply ink to the plates on the respective plaie cylinders. Above the first perfecting mechanism are arranged a pair of anglo-bars 4, while above the second peri'ecting mechanism are placed a duplicate set of angle-bars 5 and 5, the bars 5 being parallel with and directly above bars 5.

All the cylinders should be intcrgeared and driven in unison, substantially as in my patent' aforesaid, and it will facilitate undei-standing the arrangement of the web guides in the limiti-color'press by referring to 2 and 3, and following the course oi' the webs through the press as 1shown therein. The web lV is' led in, from a roll at one side oi' the machine, over the stationary guide w below the first perfectin mechanism, then up over the guide w unil between cylinders 1, and l, and l, and 3; then down between cylinders' 1a and 2; up between cylinders 2, and 2a; m81) oVoa Von one si e, and

' be an S-page or a 16-page vpaper perfected in bleliclr and with one color additional en one si( e. i

The web is preferably divided. K I nally by a slitter- 'Sv located adjacent the guide lw, and is led from said gui evs-to and overv the anglebars ll, by whichtne haltes of the web arev given atquarter-tnrii and brought into line andare then led longitndi` secondA nally 'of the press, toa-ndioverfthe y l perfecting mechanism; or, if desired, vthey could be led directly to a folder?, which is shown in this instance as located at the end of the press. 'i

Assuming that more colors aredes'iredon the paper, the split halves (a, (1,) of the web after being led to and above the second pery fecting mechanism are turned over ripper angle-bars 5a, and led out over a guide roller wend 107. and thenpassed between {agiliza-v vders 11 and 11a; then between cylinders il?" 13: Jrhen down between cylinders ll- -and 12; then 'up between cylinders 12 and.

ythe plate cylinder 1 2, so that in the arp 8 pages or 16 pages rinted in black and three colors ,in black and one color on rangement shown, could be the opposite side.

The foregoing arrangement of black and colors is based-upon the assumption that the fountains 1x and 2x su ply black inlrand Vthe o therffountain's :di erent colors; but

votherA desiredarrangementof colors may be impressed iipon the webs Yby supiiiying coloredinlrs tfo' thefountains as desire The folder is, for convenience, located at the end of the press, but obviously it could be located elsewhere,at the Vside of the pressV if desired, and lthe web could be easily led in va reverse direction over guides 'w8 to a folderl at the. side of the press,'if desired.

Qbvioiisly by the' described means and method 'of threadin "the web throughthe press, a paper coiild e printed in bloeit and in two colors witho'nt'nsing tbefcylinders v 7 n l F ',L 5 1 'w l .c Suu'. and is, and when it is not desiree te forint i longitndisienes to the full capacity of. the press in colors, one or more` of the plate cylinders can lobvioiisly be putl ont of eective operation by omitting the plates andinlr. c

Each section of the press could be used to print 'a paper Ain black and one color by threading each section as shown in Fig. 2 and running'the web directly to the folder. lt is'. obvious' 'that with the construction "shown in the 'drawings a `great variety of multicolored papers can be produced at each operation of the machine.
